Pion and kaon condensation in a 3-flavor Nambu-Jona-Lasinio model

We analyze the phase diagram of a 3-flavor Nambu-Jona-Lasinio model at finite temperature T and chemical potentials mu(u),mu(d),mu(s). We study the competition of pion and kaon condensation and we propose a physical situation in which kaon condensation could be led only by light quark finite densities.
